      dt-bindings: clk: qcom: Fix self-validation, split, and clean cruft · 2a8aa18c
      Douglas Anderson authored 
      The 'qcom,gcc.yaml' file failed self-validation (dt_binding_check)
because it required a property to be either (3 entries big),
(3 entries big), or (7 entries big), but not more than one of those
things.  That didn't make a ton of sense.

This patch splits all of the exceptional device trees (AKA those that
would have needed if/then/else rules) from qcom,gcc.yaml.  It also
cleans up some cruft found while doing that.

After this lands, this worked for me atop clk-next with just the known
error about msm8998:
  for f in \
    Documentation/devicetree/bindings/clock/qcom,gcc-apq8064.yaml \
    Documentation/devicetree/bindings/clock/qcom,gcc-ipq8074.yaml \
    Documentation/devicetree/bindings/clock/qcom,gcc-msm8996.yaml \
    Documentation/devicetree/bindings/clock/qcom,gcc-msm8998.yaml \
    Documentation/devicetree/bindings/clock/qcom,gcc-qcs404.yaml \
    Documentation/devicetree/bindings/clock/qcom,gcc-sc7180.yaml \
    Documentation/devicetree/bindings/clock/qcom,gcc-sm8150.yaml \
    Documentation/devicetree/bindings/clock/qcom,gcc.yaml; do \
      ARCH=arm64 make dtbs_check DT_SCHEMA_FILES=$f; \
  done

I then picked this patch atop linux-next (next-20200129) and ran:
  # Delete broken yaml:
  rm Documentation/devicetree/bindings/pci/intel-gw-pcie.yaml
  ARCH=arm64 make dt_binding_check | grep 'clock/qcom'
...and that didn't seem to indicate problems.

Arbitrary decisions made (yell if you want changed):
- Left all the older devices (where clocks / clock-names weren't
  specified) in a single file.
- Didn't make clocks "required" for msm8996 but left them as listed.
  This seems a little weird but it matches the old binding.

Misc cleanups as part of this patch:
- Fixed schema id to not have "bindings/" as per Rob [1].
- Listed include files as per Stephen.
- sm8150 was claimed to be same set of clocks as sc7180, but driver
  and dts appear to say that "bi_tcxo_ao" doesn't exist.  Fixed.
- In "apq8064", "#thermal-sensor-cells" was missing the "#".
- Got rid of "|" at the end of top description since spacing doesn't
  matter.
- Changed indentation to consistently 2 spaces (it was 3 in some
  places).
- Added period at the end of protected-clocks description.
- No space before ":".
- Updated sc7180/sm8150 example to use the 'qcom,rpmh.h' include.
- Updated sc7180/sm8150 example to use larger address/size cells as
  per reality.
- Updated sc7180/sm8150 example to point to the sleep_clk rather than
  <0>.
- Made it so that gcc-ipq8074 didn't require #power-domain-cells since
  actual dts didn't have it and I got no hits from:
    git grep _GDSC include/dt-bindings/clock/qcom,gcc-ipq8074.h
- Made it so that gcc-qcs404 didn't require #power-domain-cells since
  actual dts didn't have it and I got no hits from:
    git grep _GDSC include/dt-bindings/clock/qcom,gcc-qcs404.h

Noticed, but not done in this patch (volunteers needed):
- Add "aud_ref_clk" to sm8150 bindings / dts even though I found a
  reference to it in "gcc-sm8150.c".
- Fix node name in actual ipq8074 to be "clock-controller" (it's gcc).
- Since the example doesn't need phandes to exist, in msm8998 could
  just make up places providing some of the clocks currently bogused
  out with <0>.
- On msm8998 clocks are listed as required but current dts doesn't
  have them.

      clk: qcom: Don't overwrite 'cfg' in clk_rcg2_dfs_populate_freq() · 21e157c6
      Stephen Boyd authored 
      The DFS frequency table logic overwrites 'cfg' while detecting the
parent clk and then later on in clk_rcg2_dfs_populate_freq() we use that
same variable to figure out the mode of the clk, either MND or not. Add
a new variable to hold the parent clk bit so that 'cfg' is left
untouched for use later.

This fixes problems in detecting the supported frequencies for any clks
in DFS mode.

      clk: ti: clkctrl: Fix hidden dependency to node name · 6c309052
      Tony Lindgren authored 
      We currently have a hidden dependency to the device tree node name for
the clkctrl clocks. Instead of using standard node name like "clock", we
must use "l4-per-clkctrl" type naming so the clock driver can find the
associated clock domain. Further, if "clk" is specified for a clock node
name, the driver sets TI_CLK_CLKCTRL_COMPAT flag that uses different
logic for the clock name based on the parent node name for the all the
clkctrl clocks for the SoC.

If the clock node naming dependency is not understood, the related
clockdomain is not found, or a wrong one can get used if a clock manager
has multiple clock domains.

As each clkctrl instance represents a single clock domain, let's allow
using domain specific compatible names to specify the clock domain.

This simplifies things and removes the hidden dependency to the node
name. And then later on, after the node names have been standardized,
we can drop the related code for parsing the node names.

Let's also update the binding to use standard "clock" node naming
instead of "clk" and add the missing description for reg.
